Solution

1. Preparation

Tools Required:
- Socket set
- Screwdriver set
- Throttle body cleaner
- Clean cloths or shop towels
- Safety goggles
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool completely before starting the cleaning process.

2. Remove Air Intake Duct

Locate the air intake duct connected to the throttle body.
Use a screwdriver or socket to loosen the clamps securing the duct.
Carefully detach the duct from the throttle body, ensuring not to damage any connections.

3. Access the Throttle Body

Identify the throttle body mounting bolts (usually 2-4).
Use a socket to remove the bolts, taking care to keep track of them.
Gently pull the throttle body away from the intake manifold.

4. Clean the Throttle Body

Spray the throttle body cleaner directly onto the throttle plate and interior surfaces of the throttle body.
Use a clean cloth or shop towel to wipe away carbon deposits, ensuring not to leave any lint behind.
Open the throttle plate manually (if needed) to clean behind it thoroughly.

5. Reinstall Throttle Body

Position the throttle body back onto the intake manifold.
Reinstall the mounting bolts, tightening them to the manufacturer's specified torque (typically around 12-15 ft-lbs, check service manual for exact specs).
Reattach the air intake duct securely, ensuring all clamps are tight.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and let it idle, checking for any irregularities or warning lights.
